Animated WebP
BlankAI draws a single frame, so an animated WebP becomes a still image of its first frame. Keep the original if you need the animation.
WebP RIFF chunks
Remove Metadata from WebP Images
WebP is a RIFF container, and its metadata sits in separate chunks: EXIF, XMP, ICCP for color, and C2PA for Content Credentials. BlankAI writes a fresh WebP without them. Safari cannot encode WebP from a canvas, so there the clean copy is a lossless PNG instead, and the report says so.

What BlankAI removes, and what it does not
The same rules apply to every file, whatever made it. BlankAI cleans the metadata that travels with a file. It cannot reach anything that is part of the image itself.
| Layer | What it holds | BlankAI |
|---|---|---|
| EXIF and GPS | Camera or phone model, serial numbers, capture time and location coordinates. | Removed |
| XMP and IPTC | Creator tool, edit history, captions, credits and the IPTC Digital Source Type AI label. | Removed |
| C2PA Content Credentials | Who or what created the file and how it was edited, signed by the issuing app. | Removed |
| PNG text chunks | Stable Diffusion prompts, seeds and model names, ComfyUI workflows. | Removed |
| Invisible watermarks | SynthID (Google and OpenAI images), Meta's Content Seal, TikTok and ByteDance watermarks. | Not removed |
| Visible watermarks | Logos, sparkle icons and corner badges drawn onto the image. | Not removed |
| AI classifiers | Models that judge an image by how it looks. File metadata plays no part. | Not affected |
Questions
Why did I get a PNG instead of a WebP?
Safari cannot encode WebP from a canvas and returns PNG. The PNG is lossless. Use Chrome, Edge or Firefox for WebP output.
What quality is used?
92 by default. You can choose 100 or 82 before processing.
Does it keep transparency?
Yes, WebP and PNG output both keep the alpha channel.
